INVEST 91S. ENVIRONMENTAL ANALYSIS SHOWS 91S IS IN A FAVORABLE ENVIRONMENT WITH DUAL CHANNEL UPPER LEVEL OUTFLOW, MODERATE (15-20KTS) VERTICAL WIND SHEAR (VWS) AND WARM (28-29C) SEA SURFACE TEMPERATURES (SST). GLOBAL MODELS ARE IN GENERAL AGREEMENT THAT 91S WILL TRACK EAST-SOUTHEAST WHILE CONTINUING TO CONSOLIDATE AND INTENSIFY.
